I remember feeling this in regards to some early "rapid application development" software in the 90's (Visual Basic or Borland Delphi or something).
"Look how easy it is to make a text editor!" - Drag the "text editor component" over a blank form. Look how easy it is to make a web browser! - Drag the "web browser component".
Or, maybe it was in PHP, "As an example, here's code to format an integer as Roman numerals." Oh, that sounds interesting... Expecting a cool algorithm, then discover it's (for some reason) a standard library function.
